Published: October 11, 2016 | Updated: December 13, 2016

Version: 2.0

Executive Summary

This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if Microsoft Video Control fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. However, an attacker must first convince a user to open either a specially crafted file or a program from either a webpage or an email message.

This security update is rated Critical on the following client operating systems: Microsoft Windows Vista, Windows 7, Windows 8.1, Windows RT 8.1, and Windows 10. For more information, see the Affected Software section.

The update addresses the vulnerability by correcting how Microsoft Video Control handles objects in memory. For more information about the vulnerability, see the Affected Software and Vulnerability Information section.

Affected Software and Vulnerability Severity Ratings

The following software versions or editions are affected. Versions or editions that are not listed are either past their support life cycle or are not affected. To determine the support life cycle for your software version or edition, see Microsoft Support Lifecycle.

The severity ratings indicated for each affected software assume the potential maximum impact of the vulnerability. For information regarding the likelihood, within 30 days of this security bulletin’s release, of the exploitability of the vulnerability in relation to its severity rating and security impact, please see the Exploitability Index in the October bulletin summary.

[1]This update is only available via [Windows Update](http://go.microsoft.com/fwlink/?linkid=21130).

[2]Windows 10 updates are cumulative. The monthly security release includes all security fixes for vulnerabilities that affect Windows 10, in addition to non-security updates. The updates are available via the Microsoft Update Catalog.

Vulnerability Information

A remote code execution vulnerability exists when Microsoft Video Control fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

To exploit the vulnerability, an attacker would have to convince a user to open either a specially crafted file or application from either a webpage or an email message. The update addresses the vulnerability by correcting how Microsoft Video Control handles objects in memory.

Note that where the severity is indicated as Critical in the Affected Software and Vulnerability Severity Ratings table, the Preview Pane is an attack vector for CVE-2016-0142.
